Comparing the PROC & RAM performance of Ubuntu 11.04 with Windows 7

My Rig Thinkpad T420 41785ZA detail spec just google it, the only different just the RAM configuration 2 x 4GB

Comparing processor and memory perfomance using Geekbench2.1.13 in Windows 7 and Ubuntu. Only use Geekbench the 32 bit version (because the 64bit cost $19.99).

Detailed running schema + result:

• Both running in AC mode
• Windows 7 Professional 64 bit SP1 with all latest updates, power schema using Maximum Perfomance + Lenovo Turbo Boost enabled, scored 5844 http://browse.geekbench.ca/geekbench2/view/455508
• Ubuntu 11.04 Natty 64 bit with all latest updates, scored 7366 http://browse.geekbench.ca/geekbench2/view/455514

Also i test it using commonly programming language(python + mpmath with gmpy) i used:

-The Running time i give it try to run several times(executed +-5times, to see the best result, and give python(mpmath module) a chance to load(cached) into RAM)

Install OpenCL and PyOpenCL in Ubuntu 10.04 LTS Lucid Lynx 64 bit

After playing with Scientific Linux 6 with OpenCL and PyOpenCL, I decided to bring it into my primary OS, and yes it is Ubuntu 10.04 LTS Lucid Lynx 64 bit.

Searching through the net, I found two ways to install OpenCL

• by using a packaged deb made by nou at AMD dev central forum -> Ubuntu package with ATI Stream SDK
• and by installing it manually using the AMD-APP-SDK-v2.4-lnx64.tgz

Because my previous experience in SL6 is worked, so i liked to doing so within my ubuntu.

Things that needed by my system for OpenCL(testing that it works by executing 'make all' in your $AMDAPPSDKROOT -> i put it on "/home/user/AMD-APP-SDK-v2.4-lnx64/", this will built samples application that included in samples folder)

• read the guide AMD_APP_SDK_Installation_Notes.pdf (it just extract and put a conf in /etc dir)
• install libglu1-mesa-dev (in my case the package(header files) that missing is only this, so might be different on your system!), this needed when build a OpenCL samples
• also add a AMDAPPSDK in your $PATH in .bashrc file like this

Below are some screenshoot to test sample applications under AMD-APP-SDK-v2.4-lnx64/samples/opencl/bin/x86_64/ directory if the installation of AMDAPPSDK and is working:
test using HelloCL

test using GlobalMemoryBandwidth

 

and notice if running an OpenCL program using all processor thread(because i didn't have a GPU capable for OpenCL

And now for PyOpenCL(made by Andreas Klöckner at http://mathema.tician.de/software/pyopencl )
To install correctly please enable the internet connectivity its needed to install required python dependency module.

In my system is need to install libboost1.40-all-dev, python-numpy and python-libxslt. (Both are available from ubuntu repository). Using command from terminal -> sudo apt-get install libboost1.40-all-dev python-numpy python-libxslt

Installing PyOpenCl:

• download PyOpenCL from PyOpenCL
• Notice when execute configure.py : python configure.py   --cl-inc-dir=$AMDAPPSDKROOT/include   --cl-lib-dir=$AMDAPPSDKROOT/lib/x86_64   --cl-libname=OpenCL
• then -> python setup.py build
• finnally -> sudo python setup.py install

test PyOpenCL using examples benchmark-all.py

BTW  I'm just noticed that python in ubuntu is faster than in Scientific Linux 6, and it same 64 bit, same laptop.

Musing with booting time in Scientific Linux 6, Ubuntu Lucid, Windows 7

Just comparing in booting and login time between Scientific Linux 6, Ubuntu Lucid Lynx 10.04.2 LTS, Windows 7 Home Premium Service Pack 1, all system in 64 bit version.

All system already installed many software that can be used for daily activity like listening various audio formats, watching various video formats, office productivity, internet browsing, updated to the current version, installed in the same HDD(one laptop) with 4 partitions(Win 7, Ubuntu, SL, swap for Linux), development programs installed(C/C++ library, java SDK, python), converting audio/video(SL not).

Specific system configuration:

• Ubuntu mostly installed by many programs(my primary workstation), i didn't tuned it at all. Installed since it alpha version and just doing upgrade until now version 10.04.2 LTS, using live CD version 64 bit.
• SL only for fun and learning a red hat based distro. Installed from a 64 bit live DVD version.
• Windows, i use it for other software that Ubuntu not had yet, like visio, wathing HD movie using ATI vga instead using the AMD processor. And it installed an Antivirus from Microsoft Security Essential cause it rarely false alarm, and firewall using windows default, i knew it could boot faster without it, but it will make me installing windows again and again, many non Microsoft programs turned off on startup like java server, matlab server, etc. This Windows already installed when i bought the laptop, urgh yikes :( , i wonder how much the cost reduced while it not included Windows 7 :p .

The tests result

Below is the code to draw the figure(bar chart comparison) above, using Python with matplotlib module

#!/usr/bin/python

from matplotlib.pylab import arange, bar, xticks, title, ylabel, grid, show, legend

# ubuntu, sl, win
ut = [39, 7, 6]; st = [50, 10, 13]; wt = [44, 122, 20]

idx = arange(3)
wdx = 0.25

grid()
ub = bar(idx, ut, wdx, color='orange')
sb = bar(idx+wdx, st, wdx, color='red')
wb = bar(idx+wdx+wdx, wt, wdx, color='blue')
legend((ub[0], sb[0], wb[0]), ('Ubuntu 10.04', 'SL 6', 'Windows 7'))

xticks(idx+wdx, ('Booting', 'Login', 'Shutdown'))
ylabel('time in seconds')
title('Less is better')
show()

My measurement procedure:

• using stopwatch in Nokia N900 so my fingers reaction time are to be considered
• all systems booted from grub2 provided by Ubuntu lucid
• booting time measured from grub2 until it show login window
• log on time measured from pressing enter(password already entered) in login window until it show desktop and ready to use(including the LED of HDD not blinking again), well i can use(open a program) while the LED still blinking but it took the same time just like i wait LED off then open a program(yes in this case only happened with windows 7)
• just open an open office writer in all system, then close it
• shutdown time measured from pressing shutdown until the laptop turned off.

Pertama Kali Pake OS Berbasis GNU Linux

Gak kerasa, udah 3 tahun gw pake GNU Linux, waktu itu gara2 punya netbook super lemot acer aspire one a110 yg versi Linux, so default OS nya Linux, lupa distro-nya apa namanya.

Speknya Intel Atom generasi pertama yg N270, RAM cm 1 GB n gk bisa dual channel pula nih RAM, tp bkn komponen utama(CPU n RAM) yg bikin tuh laptop lemot, tapi harddisk-nya yg ternyata cm memory sejenis flashdisk yg berkapasitas 8GB dan kemampuan Read-Write-nya very poor banget dah..

Dah gitu tuh OS bawaanny buset gk bisa dibuat apa2 n gk eye catching sama sekali, paling cm utk task2 sedehana macem ketik2 kebutuhan office n dengerin MP3. Disini gw nyoba ganti ke windows XP, yah gw saat itu adalah org Indonesia yg umum sekali sebagai pengguna produk bajakan, tp FAIL, lalu gw coba ganti ke windows 7(yah bajakan lagi) n sama FAIL.

Yah FAIL, krn ternyata windows terlalu bnyk Read-Write ke harddisk, dan harddisk gw lemot puoooll, jd tuh LED indicator nyala terus n gk bisa dipake sama sekali tuh netbook jadinya.

Kemudian gw tny ama mbah Google seputar problem solving utk masalah ini, dan membawa suatu pencerahan utk menggunakan Linux pada laptop lemot ini, wah sial mana gw gk bisa Linux lg, iya kalo gw anak Informatika atw sebangsanya bakal no problem dah utk bljr OS ginian. Maka keyword selanjutnya yg gw tny ke mbah Google adlh Linux for Newbie Dumies... wkwkwkwk... Dan si mbah jawab "Ubuntu"...

Baca2 sana sini di internet utk install Linux... Dan akhirnya netbook gw yg lemot itu ternyata bisa running normal pas pake Ubuntu GNU Linux...

Waktu itu jg bnyk2 coba distro Linux lainnya, macem Fedora, PCOSLinux, OpenSuse, Mandriva, tp kayakny yg buat nubitol Linux itu Ubuntu deh...
Karena Ubuntu yg ternyata basisnya dari Debian, bisa bikin "everything just works" krn Ubuntu yg paling up to date dlm hal kompatibilitas hardware...

Mulai saat itu hingga kini, gw menemui banyak fakta yg ternyata teknologi windows yg sifatnya proprietary gak ada apa2nya kalo seandainya vendor2 hardware memberikan full support ke Linux...

Sampai saat blog ini gw tulis, gw lg pake Firefox 4 di Ubuntu Lucid Lynx 64 bit 10.04 eit tapi dengan laptop yang berbeda... Yah gw dah ganti pake Acer Ferrari One(gw namain fera) skr...

OS bawaannya yg orisini(cieh ori) tetep gw simpen, for just in case kalo ada software yg reseh cm ada utk windows...
